IccProfile help?

I cannot get IccProfile to work in Windows 2000. I have tried the
Example in the IccProfile.m comments, but iccprofile() never returns
any output.

>> file=iccprofile('filename',0)
Warning: One or more output arguments not assigned during call
to 'iccprofile'.
>> icc=iccprofile('read',file) % won't work because iccprofile does
not return anything to file variable

Also, I have another question about Icc profiles. If I use a
calibration device to generate an ICC for my monitor, and use that
ICC in my display settings in Windows, then is there any need for the
calibration tools in the PsychToolbox? The calibration is
automatically handled by the OS and ICC profile, correct?

Thanks,
Eric Angel
